To help the children appreciate the beauty of God's creation that is around them and respond with thanksgiving
By seeing the beauty and diversity in something as ordinary as a wild flower, the children will deepen their appreciation of God's gifts in creation--a necessary step in becoming good stewards of creation.
Small flowers work better than large ones because it takes more effort to really see the details in their petals and structure.
If there are children in your group with allergies or special needs (physical, visual, hearing, language, or behavioral disabilities), adapt the activity accordingly.
